Z Flag, C Flag, S Flag ..
Witch allows you to do/un-do jumps ..
Depending on witch jump .. You should edit witch you need for the exact thing ..
Examples (Most Common) ..
Code:
JNE .....
That will "operate" only if the Z Flag is not equal to 0 ..
Code:
JE
That will "operate" only if the Z Flag is equal to 0 ..
Code:
JA
That will "operate" only if the C Flag & Z Flag is ABOVE 0 ..
Code:
JB
That will "operate" only if the C Flag is below 1 ..
Code:
JG
That will "operate" only if the Z Flag & S Flag is greater then 0 ..
Code:
JGE
That will "operate" only if the S Flag is greater or equal to 0 ..
In some other cases ...
That, always jumps ..
You will have to edit the whole line of JMP ...
To what ever fits ur needs.
P.S: I'm no expert, but I hope that helped
